Patented May 4, 1943 UNITED STATES PATENT OFFICE 2 Claims.

The present invention relates to a carpenters tool of the floor jacktype.

One object of my invention is to provide a device which will permit acarpenter to apply pressure to flooring while laying the same.

Another object is to provide a device which will maintain a pressure onthe flooring while the carpenter is nailing it down.

A further object of my invention is to provide a device of the abovecharacter which will be inexpensive to manufacture, simple to repair andeasily operated.

Other objects and advantages will become apparent from the followingdescription and with reference to the drawing, wherein:v

Fig. 1 is a side elevation of the invention,

Fig. 2 is a, perspective view of the link,

Fig. 3 is a perspective view of the foot,

Fig. 4 is a perspective view of the pawl bar, and

Fig. 5 is a perspective view of a modified face block.

Referring to the drawing in detail, it will be found that A designatesgenerally a lever having a central portion I0, one end of which carriesa handle I I. The other end of the lever A carries an integral prongarranged at a substantial angle to the lever A. The lever A is providedwith a series of rack teeth I3, interjacent the handle I I and the prongI2. A link B is pivotally secured at one of its ends to the lever A,adjacent the prong I2. The opposite end of the link B has pivotallysecured thereto, a foot D. A floor engaging face plate E is secured tothe foot D by means of a dovetail joint I4. The face plate E isinterchangeable with other face plates such as the type shown at E inFig. 5.

A pawl bar C is pivotally secured to the link B at one end thereof,adjacent the foot D. The

opposite end of the pawl bar C is bifurcated as at I5 and carries a pawlI6 between the bifurcations. The central portion I 0 of the lower Aextends through the bifurcations I5 and the pawl I6 is adapted to engagethe rack I3.

In the use and operation of the present invention, the prong I2 isinserted into the surface of the joist or sub-flooring and the faceplate E of the foot D is brought into engagement with the flooring to becompressed. A downward pressure is then brought to bear on the handleII, increasing the distance between the prong I2 and face plate E. Thepawl I6 progressively engages successive teeth in the rack I3 and locksthe elements of the device in extended position, thereby enabling theoperator to use both hands in nailing the flooring.

Having thus described my invention, what I desire to secure by LettersPatent and what I claim as new, is,

1. In a device of the class described, a lever, a handle mounted on oneend of said lever, an angularly disposed prong formed integrally withthe opposite end of said lever, a rack arranged along one edge of saidlever interjacent the handie and the prong, a link pivotally secured atone end to said lever adjacent said prong, a floor engaging foot securedto the other end of said link and a pawl bar pivotally secured to saidlink adjacent said foot the opposite end of said pawl for being adaptedto engage said rack.

2. A device as claimed in claim 1 in which the floor engaging foot isprovided with an interchangeable fioor engaging face plate.
